Product Description:

The HKT50-525/A is a switched-mode power supply from Okuma’s MPS Power Supplies series for CNC control logic and I/O hardware. It provides low-voltage output so controllers, encoders, and interface cards stay within limits during spindle acceleration and axis reversal. The unit can run from plant mains or a DC bus, which supports use in machine cabinets with different incoming power arrangements.

Its primary output delivers 7.0 A, 35.0 W at +5 V, which suits processor boards and memory circuits that need steady logic power. Total output is limited to 50.0 W, helping prevent overstress of magnetic components and semiconductors. The input accepts 85 to 132 VAC, 47 to 440 Hz, allowing operation from single-phase utility service or variable-frequency sources. For DC-fed systems, the converter accepts 110 to 175 VDC.

Continuous operation is rated from 0 to +65 °C under convection cooling, so cabinet temperature affects headroom. The negative rail supplies 0.5 A, 2.5 W at -5 V for analog reference functions, while the peripheral rail provides 18.0 W at +12 V for relays and optocouplers. Output capacity follows a derating curve of 100% at +50 °C; 50% at +65 °C, which helps define thermal limits in enclosed panels. Protection includes OVP (CH1) and OCP, and the supply automatically restores output after the fault condition clears.

Wake Industrial stocks this model and offers same-day shipping on qualified orders. Every purchase includes a 1-year warranty, and quotations remain valid for 30 days. The chat tool available on the website can be used for general questions about type codes or fault codes.
